Linear referencing: How to create point/line geometry from route event table?

I need to create a point/line geometry out of the following input data:

a) route: line geometry stored with measure values, including a route id field

b) point/line event table without geometry, including a reference on the route id field, a measure value field (point event) / a start and an end measure value field (line event)

Is there an existing transformer or a common known routine in FME to solve this problem?

I you merge the two input datasets (FeatureMerger on the route id), you can use the Snipper with snipping mode = "Measure (value)" to "snip" or to cut your route geometries to a start/end value.

    Here's a great example of how to use Linear Referencing in FME!

    @david_r Can I get a copy of the sample workspace, too? I need to do the same thing.

    I'm sorry, I don't have any sample workspace for this.

     

    But feel free to post your case as a separate question, I'm sure someone can help.

    Here's a sample of how I solved it (comments in German).
